As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Please refer to FIG. 1 , which is a flowchart of a method for anti-counterfeiting identification of a battery rod according to an embodiment of the present invention. The battery pole anti-counterfeiting identification method includes part or all of the following steps.

S100: Acquire the first code according to the starting parameter of the battery rod, and send the first code to the atomizer.

In this embodiment, the start-up parameter is an initial operating parameter on the battery rod, for example, the start-up parameter is the cumulative number of various operations on the battery rod, and the start-up parameter changes with time It is convenient to generate different starting parameters at different times, so that the starting parameters of the battery rod can be random parameters, so that the numerical order of the first code is in a random state, which improves the performance of the first code. Deciphering is difficult, thereby improving the anti-counterfeiting level of the first code. In this way, after the first code is sent to the atomizer, the degree of difference between the codes received by the atomizer each time is increased, which facilitates the subsequent improvement of the anti-counterfeiting of the second code obtained from the atomizer. grade.

S200: Receive a second code sent by the atomizer, and obtain a third code according to the second code, where the second code is obtained according to the first code.

In this embodiment, the second code is obtained according to the first code on the atomizer. For example, the micro-control unit in the atomizer encrypts the first code to form the The second encoding, in the case that the first encoding has randomness, the second encoding is converted based on the first encoding, so that the second encoding also has randomness, so that the second encoding has randomness. The complexity is higher than that of the first encoding, so that the anti-counterfeiting level of the second encoding is higher than the anti-counterfeiting level of the first encoding. In this way, the second code is related to the first code, the third code is related to the second code, and after the third code is received, the second code is made to be related to the first code. Therefore, the second code is obtained through the micro-control unit in the atomizer, so that the formation of the second code is related to the encryption method of the micro-control unit of the atomizer, which is convenient for subsequent Determine the correlation between the third encoding and the first encoding, so as to facilitate the subsequent determination of the matching between the third encoding and the first encoding, and further facilitate the subsequent determination of whether the third encoding is a After the encryption of the authentic atomizer's micro-control unit, the anti-counterfeiting level of the atomizer is improved.

S300: Compare the third encoding with a preset encoding to obtain an encoding compensation amount, where the preset encoding matches the encoding corresponding to the startup parameter.

In this embodiment, the preset code corresponds to the first code. For example, the preset code is a code formed after the first code is encrypted by the micro-control unit of an authentic atomizer, so that The preset code is the code after the first code is encrypted by the atomizer matched with the battery rod, so that the preset code is a code that matches the first code and is correct. Moreover, when the atomizer is genuine, each of the first codes corresponds to a preset code, that is, the code obtained by each of the first codes through a specified encryption method is the preset code , wherein the preset codes corresponding to each of the first codes are stored in the database. When each of the first codes is encrypted by an atomizer, a second code is produced, and then the third code is formed by a specified encryption method, so that when an authentic atomizer is used, each of the first codes One code corresponds to one preset code, that is, the preset code has a one-to-one correspondence with the first code. Comparing the third encoding with the preset encoding, that is, comparing the encoding encrypted by the atomizer with the preset encoding, that is, converting the encoding encrypted by the atomizer The subsequent encoding is compared with the standard encoding, for example, a difference operation is performed between the third encoding and the preset encoding. In this way, after the difference between the two is determined, it is convenient to subsequently judge whether the atomizer is a genuine product according to the size of the coding compensation amount, thereby improving the anti-counterfeiting level of the atomizer.

S400: When the coding compensation amount is equal to 0, send a power supply continuity signal to the controller of the battery rod, so that the electrical connection between the battery rod and the atomizer is turned on.

In this embodiment, both the preset code and the third code are related to the first code, that is, the preset code is obtained after the first code is converted by an authentic atomizer, that is, the The preset code is obtained by the first code through a correct encryption method, and the third code is obtained after conversion by an atomizer that currently needs to perform anti-counterfeiting identification. According to the coding compensation amount obtained from the third coding and the preset coding, it is convenient to distinguish the degree of difference between the third coding and the preset coding, so that it is convenient to distinguish the first coding after the current The difference between the atomizer's converted encoding and the standard encoding. The encoding compensation amount is equal to 0, indicating that there is no difference between the encoding converted by the current atomizer and the preset encoding of the first encoding, that is, indicating that the first encoding has passed the current atomizer. The converted code is the same as the first code after the correct encryption method, which means that the encryption method obtained by the third code is the correct encryption method, so that the first code is converted by the atomizer. The latter code is the correct code, so it is determined that the sending object of the first code is an authentic atomizer. In this way, after it is determined that the atomizer used by the battery rod is a genuine atomizer, the power supply conduction signal sent is used to conduct the electrical connection between the battery rod and the atomizer, so that the The battery in the battery rod supplies power to the atomizer through the electrode column, so that the atomizer starts to work normally.

In one of the embodiments, the obtaining the first code according to the starting parameter of the battery rod includes: obtaining the first code according to the clock parameter of the battery rod. In this embodiment, the startup parameter is a clock parameter, and the clock parameter is the count of the micro-control unit in the battery lever, that is, the startup parameter is the clock signal of the micro-control unit in the battery lever corresponding opening time. In order to improve the anti-counterfeiting level of the first code, by increasing the randomness of the startup parameters, the acquisition of the startup parameters does not have any regularity, reducing the identity of the initial parameters of the battery rod, thereby improving the the anti-counterfeiting level of the first code. Moreover, since the time of starting the battery rod is a variable, the first code can be changed according to the needs of use, so that the first code generated by the battery rod activated at each moment is different. For example, the clock parameter can be Take any time between 0:00:00 (00:00:00) and 23:59:59 (23:59:59) as the startup parameter; for another example, the current time is 21:52:23 (21:52:23), the first code is 0x215223. According to different start-up moments, the corresponding first code changes, which improves the anti-counterfeiting level of the battery rod anti-counterfeiting identification method.

In one embodiment, the acquiring the first code according to the activation parameter of the battery rod includes: acquiring the first code according to the number of sucking mouths of the battery rod. In this embodiment, the activation parameter is the number of suction ports, and the number of suction ports is the number of times the suction nozzles in the battery rod are used, that is, the activation parameter is the number of times that the air in the battery rod flows through the ventilation channel. . In order to improve the anti-counterfeiting level of the first code, by increasing the randomness of the startup parameters, the acquisition of the startup parameters does not have any regularity, reducing the identity of the initial parameters of the battery rod, thereby improving the the anti-counterfeiting level of the first code. Moreover, since the number of times of using the battery rod is a cumulative increment, that is, a variable, the first code can be changed according to the needs of use, so that the first code generated every time the battery rod is used is different, for example, The number of sucking mouths is any value between 0 and 9999; for another example, when the current number of sucking mouths is 99, the first code is 0x0099. According to different start-up moments, the corresponding first code changes, which improves the anti-counterfeiting level of the battery rod anti-counterfeiting identification method. In another embodiment, the startup parameter includes the clock parameter and the number of sucking mouths, and the corresponding first code is a combination of the clock parameter and the number of sucking mouths, for example, the current time is 21:52 23 minutes (21:52:23), when the number of sucking mouths is 99, the first code is 0x2152230099, which increases the number of types of the first code and further improves the randomness of the first code. The anti-counterfeiting level of the battery rod anti-counterfeiting identification method is further improved.

In one embodiment, the obtaining the first code according to the start-up parameter of the battery pole includes: obtaining the initial state code according to the start-up parameter; and performing an initial encryption operation on the initial state code to obtain the first code. In this embodiment, the initial state code includes various state parameters of the battery rod, and the initial state code is the current state parameters of the battery rod, which are used to reflect the status of the battery rod in real time. For each current state, these state parameters are parameters that change with time, and only if any one of the parameters changes, the first code can be changed. The initial encryption operation is performed on the initial state code, that is, the specified operation is performed on various state parameters of the battery rod. When there are more types of the initial state code, the irregularity of the first code is stronger. , so that the disorder of the first encoding is enhanced, so that the anti-counterfeiting level of the third encoding obtained through the first encoding is improved.

Further, the performing an initial encryption operation on the initial state code includes: cyclically shifting the initial state code to the right by a preset number of code bits. In this embodiment, the initial state code includes the clock parameter of the battery rod and the number of sucking mouths, the current time is 21:52:23 (21:52:23), and when the number of sucking mouths is 99, the initial state The code is 0x2152230099, and the initial state code is cyclically shifted to the right by 3 bits, wherein the initial state code is correspondingly converted into a binary code, and then the code is cyclically shifted to the right, and the obtained first code is 0x242a446013. In this way, after performing a cyclic right-shift operation on the initial state code, the first code is different from the initial state code, and one-time encryption of the initial state code is implemented, so that the code sent to the atomizer is To encrypt the code, the security level of the code sent to the atomizer is increased.

In one embodiment, the obtaining the third code according to the second code includes: performing a decoding operation on the second code to obtain the third code; and combining the third code with a preset Comparing the encodings includes: comparing the third encoding with the first encoding. In this embodiment, the second code is a code converted by the atomizer, for example, the atomizer encrypts the first code to obtain the second code. The third encoding is used to compare with the preset encoding, and perform a decoding operation on the second encoding, that is, decrypt the second encoding, so that the third encoding is converted into a corresponding encoding, which is convenient for comparison with the second encoding. Compare with the above preset codes. In this embodiment, the preset code is the first code, and the decoding operation for the second code is to decrypt the code returned by the atomizer to the battery rod according to the specified For example, the decryption method is opposite to the encryption method; for another example, the encryption method is a cyclic right shift of the encoding, and the decryption method is a cyclic left shift of the encoding; another example, the encryption method The method is to perform addition and multiplication operations on the encoding respectively, and the decryption method is to perform division and subtraction operations on the encoding. In this way, the decoding operation is the reverse encryption of the encrypted code, so that the third code is decrypted into a corresponding code, so as to be compared with the first code, so that the decoded The comparison between the third code and the first code to the same extent is convenient to determine whether the currently used atomizer is genuine, and to realize the anti-counterfeiting of the current atomizer used in conjunction with the battery rod.

In one of the embodiments, the comparing the third code with a preset code to obtain a code compensation amount, and then further comprising: when the code compensation amount is greater than or less than 0, controlling the battery rod The device sends a power disconnection signal, so that the electrical connection between the battery rod and the atomizer is disconnected. In this embodiment, if the code compensation amount is greater than or less than 0, it indicates that the third code does not match the preset code, that is, it indicates that the third code is a code that has passed through a non-genuine atomizer. Obtained after encryption, at this time, the atomizer used with the battery rod is a non-genuine atomizer. In order to avoid the bad use caused by the use of non-genuine atomizers, by sending a power supply disconnection signal to the controller of the battery rod, the controller disconnects the battery rod from the atomizer, so that the battery rod is disconnected from the atomizer. The electrical connection state between the battery rod and the atomizer is set to a disconnected state, so as to control the battery in the battery rod not to supply power to the atomizer, thereby confirming that the currently used atomizer is a non-genuine product The atomizer further improves the anti-counterfeiting level of the atomizer.

In one embodiment, the step of receiving the second code sent by the atomizer further includes: detecting whether the return code is received within a preset time; when the return code is not received within the preset time, A re-acquisition signal is sent to the controller of the battery pole to re-acquire the first code. In this embodiment, the return code is the second code, because some non-genuine atomizers do not have a micro-control unit inside, that is, these non-genuine atomizers cannot communicate with the battery rod. There is data transfer between them. In this way, after each time the first code is sent out, the micro-control unit of the battery rod will wait for the return data from the atomizer within the preset time, and will not receive any data within the preset time. The above-mentioned return code indicates that the current atomizer is a non-genuine atomizer, and the subsequent comparison with the preset code cannot be performed. At this time, the first code is re-acquired to perform anti-counterfeiting for the next atomizer to be used. It is convenient to screen out non-genuine atomizers without micro-control units, and further improves the anti-counterfeiting level of atomizers.

In one embodiment, the obtaining the first code according to the start-up parameter of the battery pole further includes: detecting whether the operating state of the battery pole is an on state; when the operating state is an on state, obtaining the Startup parameters for the battery lever. In this embodiment, the ON state is that the operating state of the battery rod is the activated state, that is, the micro-control unit of the battery rod is in the working state, that is, the micro-control unit of the battery rod is not in the dormant state. By determining the operating state of the battery rod, it is convenient to accurately start the micro-control unit of the battery rod, so as to facilitate subsequent encryption and decryption of each code, thereby facilitating the opening of the battery rod when it is in use, reducing the need for the Power consumption of the microcontroller unit.

The anti-counterfeiting process is described in detail below, and the atomizer used is a genuine atomizer.

Example: the startup parameters are the clock parameters of the battery lever and the number of sucking mouths, the current time of the battery lever is 21:52:23, that is, the clock parameter of the battery lever is 21:52:23, and the number of sucking mouths is 99. The code composed of the startup parameters is 0x2152230099, and the startup parameters are rotated to the right by 3 bits, and the first encoding obtained is 0x242a446013; the first encoding is encrypted by the genuine atomizer, that is, the first encoding One code is cyclically shifted to the left by 6 bits, and the obtained second code is 0x0a911804c9; the decoding operation is performed on the second code, that is, the second code is cyclically shifted to the right by 3 bits, and the obtained third code is 0x2152230099, The preset encoding is an encoding composed of startup parameters, and the difference between the third encoding and the preset encoding is the encoding compensation amount. In this way, only when the atomizer used is a genuine product, the final obtained code compensation amount can be 0. By encrypting and decrypting the startup parameters, the compatibility between the atomizer and the battery rod is connected, and then the matching of the atomizer and the battery rod is connected. The evaluation of the code compensation amount is convenient to determine whether the encryption of the first code by the atomizer is the specified encryption method, so as to determine whether the currently used atomizer is genuine, so that it can be used normally only when the atomizer is genuine. , which improves the anti-counterfeiting level of the atomizer.

It is understandable that when there are few types of startup parameters used by the micro-control unit of the battery rod, it is easy to directly decipher after limited operations. If the types of collected startup parameters are increased, it will undoubtedly increase the size of the battery rod. The power consumption of the micro-control unit is higher, and even a processor with higher computing speed and computing precision is required, which increases the manufacturing cost of the battery rod. However, the startup parameters collected by the micro-control unit of the battery rod are all random, that is, related to the use time and the number of times of use. increase. Therefore, in the encrypted first code output by the micro-control unit of the battery rod, it is necessary to increase the anti-counterfeiting level of the first code by adding some specific codes, which increases the difficulty of cracking the processor of the non-genuine atomizer. .

In order to further improve the anti-counterfeiting level of the atomizer and reduce the probability of cracking the first code, the obtaining of the first code according to the startup parameters of the battery rod includes the following steps, that is, step S100 includes the following steps:

Obtain the initial code according to the startup parameter;

Get the output pin number of the microcontroller unit of the battery pole;

The first code is obtained by inverting the code bit corresponding to the output pin number in the initial code.

In this embodiment, the initial code is formed by the arrangement and combination of parameters corresponding to each start-up state of the battery rod, and the initial code is a regular code. For example, the start-up parameter is the clock parameter of the battery rod and The number of sucking mouths, the current time of the battery rod is 21:52:23, that is, the clock parameter of the battery rod is 21:52:23, the number of sucking mouths is 99, and the initial code composed of the startup parameters is 0x2152230099. After knowing its arrangement and encryption method, the micro-control unit of the non-genuine atomizer can be cracked in a limited number of arrangements and combinations. The output pins of the micro-control unit of the battery rod can be adjusted according to actual needs, and the output pins of the micro-control unit of each battery rod can be randomly set on the production line when the battery rod is assembled, that is, the battery rod There are differences in the output pin numbers of the microcontroller units. However, before the micro-control unit of the battery rod outputs the signal, the corresponding output pin number can be obtained directly. After the output pin number of the microcontroller unit of the battery pole is obtained, the output pin number is unique, that is, the output pins of the microcontroller unit of the battery pole are different, so as to ensure the output of the microcontroller unit of each battery pole end is different.

The output pin number corresponds to a specific value, and the inverse code operation is performed on the initial encoding according to the output pin number, that is, the corresponding code position of the output pin number in the initial encoding is selected, and this code position is carried out. Negate the code, so that the values corresponding to at least one code bit in the first code are different. For example, when the output pin number is 1, the first code bit of the code composed of the startup parameters is inverted, that is, the "9" in it is inverted to obtain "6", wherein the startup parameter The binary code corresponding to the first code bit of the composed code is 1001, and the binary code after its inversion is 0110. After the cyclic right-shift operation on the initial code, the obtained first code is 0xc42a446012. In this way, the first code that has not performed the above operation before is 0x242a446013. Compared with the first code performed in this step, the values of two code bits have changed, so that the complexity of the first code obtained after this step is improved. , so that the encryption level of the first code is improved, and the anti-counterfeiting level of the battery rod anti-counterfeiting identification method is further improved.

Moreover, the output pin number is the number corresponding to the output pin of the micro-control unit in the battery rod. Even if the encryption method of the above-mentioned negation code is known, in order to know the output pin number, the battery The rod is destructively disassembled, which is impossible for users of non-genuine atomizers, thereby effectively reducing the usage rate of non-genuine atomizers and improving the anti-counterfeiting level of non-genuine atomizers.

Further, the atomizer is connected to the battery rod for use, and during long-term use, the e-liquid in the atomizer is atomized into vapor-like smoke, that is, e-liquid droplets with small particle size, which are in the battery. The air channel of the rod circulates in the air channel, which is easy to penetrate and adhere to the signal end, so that the signal output end and the signal input end are short-circuited, so that the output of the signal is the same as the input, and the transmission of the signal is disordered. The atomizer was misjudged as a non-genuine atomizer.

In order to reduce the misjudgment probability of the genuine atomizer, the following steps are included after receiving the second code sent by the atomizer:

Detecting whether the second encoding is the same as the first encoding;

When the second code is the same as the first code, within a preset return period, receive the verification code returned by the atomizer;

Detecting whether the verification code is the same as the first code;

When the verification code is different from the first code, the verification code is replaced with the second code.

In this embodiment, the second code is the code returned by the atomizer, that is, the code output by the output end of the atomizer, that is, the code received by the input end of the battery rod. After the output end of the battery rod outputs the first code, the first code is processed by the micro-control unit in the atomizer, and the encrypted code is returned to the battery rod. When there is e-liquid between the input end and the output end of the battery rod, under the electrical conductivity of the e-liquid, the output electrical signal of the output end of the battery rod is guided to the input end of the battery rod through the e-liquid, It is easy to cause the first code and the second code to be the same, so that the micro-control unit of the battery rod mistakenly thinks that the current atomizer is a non-genuine atomizer. The comparison between the first code and the second code is convenient for determining the situation that the output end and the input end of the battery rod are short-circuited by e-liquid. In order to reduce the probability of misjudgment of the atomizer, after the second code is the same as the first code, within a preset return period, re-acquire the code returned by the atomizer once, that is, the Verify code. Since the input end and the output end of the battery rod are short-circuited, the code processed by the micro-control unit of the atomizer will be returned with a lag, that is, the code processed by the micro-control unit of the atomizer will be later than the e-liquid input. The coding of the MCU of the battery pole. Therefore, by re-acquiring the verification code returned by the atomizer once, it is convenient to determine whether the code obtained before the battery rod is the code encrypted by the atomizer.

The verification code is different from the first code, which indicates that the input end and the output end of the battery rod are short-circuited. Moreover, the code returned after the first code is encrypted by the atomizer is returned with a lag. In this way, the verification code can be identified as the code processed by the atomizer, and replaced with the second code, that is, the verification code is the second code before the final conversion to the third code, so that The second code returned by the authentic atomizer is received by the micro-control unit of the battery rod, which reduces the probability of misjudging the authentic atomizer as a non-authentic atomizer.

In other embodiments, when the micro-control unit of the non-genuine atomizer is only a data forwarding device, the second code received by the battery rod is still the same as the first code, and the above steps are still performed at this time. However, to detect whether the verification code is the same as the first code, the subsequent steps are as follows:

When the verification code is the same as the first code, a power supply disconnection signal is sent to the controller of the battery rod, so that the electrical connection between the battery rod and the atomizer is disconnected.

At this time, it can be directly determined that the current atomizer is not genuine, and the electrical connection between the battery rod and the atomizer is disconnected to prevent the battery of the battery rod from supplying power to the heating wire in the atomizer. , further improving the anti-counterfeiting level of the battery rod anti-counterfeiting identification method.

The present application also provides a battery rod, which includes a casing, an output electrode column, a main control board, and a battery. The casing is provided with a through hole. The output electrode column passes through the through hole, and the output electrode column is used for electrical connection with the atomizer. The main control board is arranged in the casing. The output end of the main control board is connected with the output electrode column. The main control board is configured to send the first code to the atomizer, receive the second code sent by the atomizer, and obtain the third code according to the second code.
